Dear RockinWagin:

The color (dye) has nothing to do with any capability of an antifreeze solution. It's just used to distinguish between various kinds of antifreeze.

You can read my posts in the following threads to understand why distilled/deionized water is the best for mixing with antifreeze, and the actual differences between various kinds of antifreeze such as conventional green antifreeze, Japanese (green | orange | purple) antifreeze, European antifreeze (Clear, Blue, Yellowish, Orange) G-05, G11, G12, G48 etc...

Antifreeze changed..
